mvp
Allows arithmetic operators to be used for multivariate polynomials such as addition, multiplication, integer powers, etc.
# S3 method for mvp Ops(e1, e2) mvp_negative(S) mvp_times_mvp(S1,S2) mvp_times_scalar(S,x) mvp_plus_mvp(S1,S2) mvp_plus_numeric(S,x) mvp_eq_mvp(S1,S2) mvp_modulo(S1,S2)
The high-level functions documented here return an object of
mvp, the low-level functions documented at lowlevel.Rd
lowlevel.Rd
return lists. But don't use the low-level functions.

The function Ops.mvp() passes unary and binary arithmetic operators “+”, “-”, “*” and “^” to the appropriate specialist function.
Ops.mvp()
+
-
*
^
The most interesting operator is “*”, which is passed to mvp_times_mvp(). I guess “+” is quite interesting too.
mvp_times_mvp()

(p1 <- rmvp(3)) (p2 <- rmvp(3)) p1*p2 p1+p2 p1^3 p1*(p1+p2) == p1^2+p1*p2 # should be TRUE
